    Question Confused by partitions - dual boot Windows 8 and Ubuntu 12.10

    I'm trying to install Ubuntu 12.10 alongside Windows 8.

    I get to the partition part of the installation and there are about 7 partitions already there!

    I've attached a screenshot from my phone.

    Where do I put my Ubuntu install? There are like 3 NTFS partitions...

    Many thanks for your help

    Re: Confused by partitions - dual boot Windows 8 and Ubuntu 12.10

    You need to use Windows MMC to shrink your main Windows install to make room for Linux. Ubuntu cannot use Windows partitions for any system partitions. With gpt you do not have to worry about primary partitions as they all are the same with gpt partitioning.
    Reboot Windows after shrink to let it update itself and run chkdsk.

    In UEFI/BIOS be sure to turn off secure boot & fast boot.

    You will need to use the 64 bit version of 12.10 and from the UEFI menu boot the flash drive in UEFI mode. That way it will install in UEFI mode.
    Systems need quick boot or fast boot turned off in UEFI settings. Vitial for some systems.

    Ubuntu's default install is / (root) and swap. You may want additional partitions for /home and/or a NTFS data partition. If you put most data in a shared data partition you probably do not need the separate /home.

    You don't have any free space (unallocated) on the disk. You need unallocated space to create the linux partitions in it. How you create it is your choice. If shrinking the win8 partition it's best to use windows Disk Manageent and reboot few times after it's done.

    Also make sure you read about win8 and 12.10 dual boot first, there are some issues and procedures to follow.

    For example this is similar thread where oldfred posted useful links:

    Re: Confused by partitions - dual boot Windows 8 and Ubuntu 12.10

    EDIT: I partitioned the drive and installed Ubuntu 12.10 but.... now GRUB2 won't load... when I restart it skips to a purple screen and loads straight into 12.10 (with absolutely no option to boot into Windows 8)

    I followed the UEFI settings so I'm not too sure what's causing this.

    Grub2's os-prober has a bug that it does no create a correct chain load entry. But you do not even have the incorrect one's? When only one system is detected, it will not show the grub menu. Perhaps they have started to fix the issue but only stopped the incorrect entries?

    Boot-Repair should still add the correct chain entries or you can manually add them. Bug report has examples of manual entries or we can help you if you do not use Boot-Repair.

    Boot-Repair has options to add the Boot-Retries. Also some UEFI only Boot Windows and Boot repair renames & backs up some of the files to make it work. Probably best for you to back up the entire efi partition first.

    Thanks for your reply.

    Sorry if I'm being dense; are you suggesting I use boot repair (recommended repair)?

    Yes, It will find the Windows efi entry and add a Windows efi chain load boot stanza to 25_custom. Then you should be able to boot either Windows or Ubuntu.
